Subject: [PATCH] arm: mvebu: use the main timer as clock source from DT

This commit:
  573145f08c2b92c45498468afbbba909f6ce6135
  clocksource: armada-370-xp: Use CLOCKSOURCE_OF_DECLARE

replaced a call to the driver's timer initialization by a call to
clocksource_of_init(). However, it failed to select CONFIG_CLKSRC_OF.

Fix this by selecting CONFIG_CLKSRC_OF for Armada370/XP machines.
Without this change the kernel is stuck at: 'Calibrating delay loop...'.
